Which type of RNA carries amino acids to the ribosome used in polypeptide creation?
A
tRNA.
B
rRNA.
C
mtDNA.
D
mRNA.
Verified step by step guidance1
Understand the role of each type of RNA in protein synthesis: mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA).
mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.
rRNA is a component of ribosomes and plays a role in catalyzing the formation of peptide bonds.
tRNA is responsible for transporting amino acids to the ribosome, where they are added to the growing polypeptide chain.
Identify that tRNA is the type of RNA that carries amino acids to the ribosome for polypeptide creation.
